Abstract

This study aims to know the description of mathematical communication skills in terms of students' mathematics ability in class IX in solving problems on the subject of quadratic equations. The type of research is qualitative research with a descriptive approach. There were 6 research subjects namely two students that have high-ability, two students that has medium-ability, and two students that has low ability. The instruments used in data collection are written tests and interviews. The results showed that subjects with high mathematical abilities were sufficiently able to describe and state problem situations in written or image form properly, were able to use mathematical symbols and terms appropriately and were able to connect algebraic expressions into mathematical ideas. Subjects with moderate mathematical abilities are able to use mathematical symbols and terms appropriately but are less able to describe and state problem situations in written or image form properly and are also less able to connect algebraic expressions to mathematical ideas. Subjects with low mathematical abilities are not able to describe and state problem situations in written or image form properly and correctly, are less able to use mathematical symbols and terms appropriately and have not been able to connect algebraic expressions into mathematical ideas. The results of this study are expected to add insight and improve students' mathematical communication skills, especially in solving math problems related to the application of everyday life.

Abstract

This study aims to measure the quality of the JadwalIbadah website based on usability quality, information quality, and interaction quality on user satisfaction. The method used in this research is WebQual 4.0. Based on the WebQual 4.0 method, there are three variables, namely usability, information quality, and interaction quality on user satisfaction. The results showed that the variables usability (X1), information quality (X2), and interaction quality (X3) where each independent variable had 90% effect on user satisfaction (Y) on the JadwalIbadah website. While the rest is influenced by external variables other than the webqual 4.0 variable. Based on the results of the analysis conducted, there is a positive relationship between the services provided by the JadwalIbadah website to the three variables, namely usability (X1), information quality (X2), and interaction quality (X3) so that the results are positive on user satisfaction (Y). So that the three variables have a significant effect on the quality of the Schedule of Worship website on user satisfaction (Y).
